Google doodles: A gallery of the search engine's most obscure special logos (SLIDE SHOW).

Wait, That Says "Google"?!

Today's Google doodle celebrates Robert Bunsen. Here are some other obscure doodles.

The complicated and interactive Google doodle for March 31 celebrates Robert Bunsen's 200th birthday. Back in 2009, The Big Money took a look at the most obscure Google doodles in the company's history, including doodles to mark the birthdays of Dr. Seuss and Jackson Pollock.

It seems pretty unfathomable that 10 years ago most people had no idea what Google (GOOG) was. Needless to say, now that its home page is among the most-viewed pages on the Internet, its brand is fairly well-known. But has Google become too smug about just how recognizable its name is? Its increasingly obscure daily logos suggest that might be the case. This logo, for example, ran in June to celebrate the 25th anniversary of the video game Tetris. While game enthusiasts might have been amused, lots of people were probably just puzzled.

On May 18, 2008, Google celebrated the 125th birthday of Walter Gropius, a renowned architect known for incorporating modern technology into his building designs.

Google written in Braille appeared on the home page on Jan. 4, 2006. A nice tribute to Louis Braille, who created a reading system for the visually impaired, perhaps, but the color-coded signage is useless to anyone for whom Braille is actually intended.

Google celebrated the Persian New Year on March 20, 2006, with a capital G followed by traditional symbols of the holiday. This is among a handful of logos that upset some people who complained that Google did not alter the logo for some important U.S. holidays, while recognizing other countries' special days.

Google posted this logo on its search page on July 12 in selected countries in honor of Pablo Neruda, Chilean poet and politician.This illustration seems to allude to his anthology On the Blue Shore of Silence. Soul searching meets Web searching—how poetic!
